Shade Tree Micro Aviation pushed the limits of X-Plane to make the U-2S as realistic as possible. When you read the owner’s manual you will see that we relied on a number of sources to complete the project. We acquired the best books available and researched every picture we could find to make the cockpit authentic. The principal modeler spent more than 2 years researching this plane and consolidating the information into the flight and 3D model. The skin textures are masterfully created to replicate two actual aircraft in service.

North American Rockwell OV-10 Bronco

The North American Aviation Rockwell OV-10 Bronco is a turboprop light attack and observation aircraft. It was developed in the 1960s as a special aircraft for counter-insurgency (COIN) combat, and one of its primary missions was as a forward air control (FAC) aircraft. It can carry up to three tons of external munitions, and loiter for three or more hours.

STMA presents an update to its popular v8 OV-10A model for XP v 9.70 and v10.04r3+.

The U.S. Army Air Force AT-11 & U.S. Navy SNB-1 KANSAN

Identified by their unique bulbous nose with it’s bombardier’s station, the AT-11/SNB-1 has a storied history. This extract from the Wikipedia Article says it all: During and after World War II, over 4,500 Beech 18s saw military service—as light transport, light bomber (for China), aircrew trainer (for bombing, navigation and gunnery), photo-reconnaisance, and "mother ship" for target drones—including United States Army Air Forces (USAAF) AT-11 Kansan; and United States Navy (USN) UC-45J Navigator,SNB-1 Kansan. In World War II, over 90% of USAAF bombardiers and navigators trained in these aircraft.

Sherpa K650T Turboprop

The turbine Sherpa (K650T) is our newest addition to the bush plane lineup. This amazing aircraft was designed and built by Byron Root and Glen Gordon and is now undergoing the arduous phases of certification. We tapped the Sherpa information sources and developed a set of models that closely follow the turbine Sherpa’s performance. It is impressive! With a proprietary airfoil and flap design, 3500 pound empty weight, 840 horsepower turning 110 inches of three-blade prop you know it has to be good.

Aviat A-1C Husky

We are pleased to present the Aviat A-1C Husky. The Aviat Husky is a two-seat, high-wing, utility light aircraft built by Aviat Aircraft of Afton, Wyoming. It is the only all-new light aircraft that was designed and entered series production in the United States in the mid to late 1980s. The latest evolution of the Husky is the A-1C with improved wing features and added power and lift/drag characteristics for improved bush flying perfomance.

de Havilland DHC-2T Turbo Otter

Viking Air, Ltd, a long time Canadian parts supplier to de Havilland Canada, purchased all of the rights to and have continued upgrading and developing new variants of the trusty DHC2 Beaver after DHC closed its doors. The latest model is the DHC2T Turbo Beaver powered by the ultra-reliable Pratt & Whitney PT6 turboprop engine

STMA’s K-MAX Helicopter

The Kaman K-MAX (Company designation K-1200) is an American helicopter with intermeshing rotors built by Kaman Aircraft. It is optimized for external load operations, and is able to lift a payload of over 6,000 pounds, which is more than the helicopter's empty weight.

Pilatus PC-12/47

The Pilatus PC-12 is a single-engine turboprop passenger and cargo aircraft manufactured by Pilatus Aircraft of Switzerland. The main market for the aircraft is corporate transport and regional airliner operators.

Beech 18

A SPECIAL DEDICATION: We are dedicating this model to our good friend and fellow X-Plane modeler, Heinz Dziurowitz, myvirtualhanger.com, who created the Beech 18 Model and who unexpectedly passed away Wednesday, May 13th, 2015. He was a gentleman, a skilled modeler, and a good friend. He will be missed.

de Havilland DHC-3 Otter

The de Havilland DHC-3 Otter is a single-engined, high wing, propeller-driven, STOL aircraft developed by de Havilland Canada. It was conceived to be capable of performing the same roles as the earlier and highly successful Beaver, but was overall a larger plane.

The Otter is a great plane for Bush Flying. Similar to the Beaver but caries a larger load.

Our business goal is to have fun turning out quality X-Plane models.We build retail models for sale at X-Plane.org’s store and custom models for leading aviation and aviation simulation companies world-wide.

Some of our models are donationware. We won't bug you about payment, but if you find our products worthy, a donation of $2.50 will earn you a place on our good guys list, earn our eternal gratitude, and give you one of the best X-Plane models available to fly.

We are extremely pleased that our models are featured in the X-Plane.org Store. You can browse through our model pages and click the Buy Now button to pay at the store or do your shopping at the Store and use their shopping cart to make multiple purchases. Please note that if there's a conflict, the Store prices are current.

To better serve our customers we have created ourPlugin Update Bin, or PUB, where we announce the latest on STMA projects, patches and links to updated plugins. Bookmark the PUB and check periodically for all the news.

We are also pleased to support Alpha Trainer. Alpha Trainer is a plugin for X-Plane that helps new simulator as well as student pilots better understand the physics of flight. For more information and to order Alpha Trainer go to the Alpha Trainer website.

If you would like to make a general donation in any amount, please click the make a donation link below. Your support is much appriciated!

NOTICE: Using a Beta or Release Candidate (RC) X-Plane version? Please don't contact us about model problems, unless you are just passing along the information. Betas and RC don't have all of their features enabled and are, by definition, buggy so we can not make any changes until the final, stable XP version is released. If you have the disc space, we strongly recommend that you keep at least one recent stable version of X-Plane installed in addition to any such Betas.

News and Events

Our PC12 has the best flying characteristics of any PC12 available for X-Plane and that the cockpit instruments are virtual replicas of the real airplane’s instrument panel. No other model permits performing autopilot-coupled VOR, ADF/NDB, and RNAV (GPS) navigation & approaches using a realistic EFIS for controlling the flight.

We have stopped creating models in XP10 to concentrate all of our efforts on XP11. Our XP11 models and our Beech AT11 & D18S, DHC3, PC12_47G, which are XP10.5 models but are fully compatible with XP11, are equipped with our unique AutoUpdate plugin. We will continue to support our earlier models and fix all identified bugs for their economic lifetimes.

We have successfully developed and released 64 bit versions of all of our plugins and add-ons. See our Plugins Update Bin for details on all plugins.

Batch Airfoil Update:

We strongly recommend that you open V9.7 Airfoil Maker and do a batch airfoil update on all of your custom models before copying them in to X-Plane V10. If any of our airfoils fail this test please notify us immediately..
